How difficult is it to change one’s behavior, like the suppression of anger? How difficult is it for one to resist anger when confronted with obstacles? God compared these evils of the mind to dusts that accumulate on physical surfaces. When dust is light, it is easy to wipe away; but when dust has accumulated, it is very difficult to clean. If you have a ceiling fan, you will easily understand this analogy. This is why it is difficult to change a person who has heavily accumulated evil, like anger or greed. To remove these evils will require much vigilance and effort by the individual.
To the disappointment of many religious people, the acceptance of God does not eliminate the evils in our minds. It is through God that we can change our mindset. God helps us sweep these evils away. How does God help us remove these evils? The Western religions may say that God tests us; while the Eastern religions believe God guides us by causality (karma). But at the end, it is the individual that must sweep these evils by him or herself.
It is not surprising that some who claim to have found God regresses at times where others find fault in the person. It is not the teaching that does not stand, but it is the accumulated dusts that often make it difficult for the individual to purify his or her mind when challenges or suffering occurs. In the Book of Prophecy (Ofudesaki), God tells us that this path is a very difficult path; but he promises that the rewards are great!
